Reduced Exposure Study Using THS 2.2 Menthol With 5 Days in a Confinement Setting Followed by 86 Days in an Ambulatory Setting

March 11, 2020 updated by: Philip Morris Products S.A.

A Randomized, Controlled, Open-label, 3-arm Parallel Group, Multi-center Study to Demonstrate Reductions in Exposure to Selected Smoke Constituents in Apparently Healthy Smokers Switching to the Tobacco Heating System 2.2 Menthol (THS 2.2 Menthol) or Observing Smoking Abstinence, Compared to Continuing to Use Menthol Conventional Cigarettes, for 5 Days in Confinement and Prolonged by 86 Days in an Ambulatory Setting

Evaluate if the ad libitum use of the THS 2.2 Menthol (mTHS), a candidate Modified Risk Tobacco Product, for 5 days in confinement, and after 86 days in an ambulatory setting, by apparently adult healthy smokers results in a reduction in the levels of biomarkers of exposure (BoExp) to selected harmful and potentially harmful constituents (HPHCs).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The main goal of the study is to evaluate if the ad libitum use of the THS 2.2 Menthol (mTHS) for 5 days in confinement, and after 86 days in an ambulatory setting, by apparently adult healthy smokers results in a reduction in the levels of biomarkers of exposure (BoExp) to selected harmful and potentially harmful constituents (HPHCs) compared to smokers continuing smoking their own preferred brand of menthol conventional cigarette (mCC) and smoking abstinence (SA). Smokers who remained abstinent from SA were used as a benchmark to provide context to the exposure reduction.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

22 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

  • Subject has smoked for at least the last 3 consecutive years.
  • Subject does not plan to quit smoking within the next 6 months.

Exclusion Criteria:

  • As per Investigator judgment, the subject cannot participate in the study for any reason (e.g., medical, psychiatric, and/or social reason).
